Legal claims defining the scope of protection, as filed with the USPTO.

1

1. A method of wireless communication, comprising: providing, by a user entity, interference information to a macro node, wherein the interference information provided by the user entity includes information relating to interference cancellation capabilities of the user entity, and the interference cancellation capabilities include one or more of: a restriction type of transmission and a number of transmissions that the user entity is capable of canceling; and receiving a communication scheduled by a base station, wherein the communication is conveyed on a quasi-ABS which includes information corresponding to at least one macro set of data from the macro node, said macro set being made active on the quasi-ABS based at least in part on the interference information.

2

2. The method of claim 1 further comprising cancelling interference corresponding to information which is included in the at least one macro set.

3

3. A method of wireless communication, comprising: providing, by a user entity, interference information to a macro node; receiving a communication scheduled by a base station, wherein the communication is conveyed on a quasi-ABS which includes information corresponding to at least one macro set of data from the macro node; and cancelling interference corresponding to information which is included in the at least one macro set, wherein the at least one macro set includes a restricted data transmission from the macro node, and the data is restricted to include data having at least one of: a pre-selected priority, a pre-selected a transmission mode, a minimum traffic to pilot ratio, or a specified modulation and coding property.

4

4. The method of claim 3 wherein the data is restricted to include data having a pre-selected priority.

5

5. The method of claim 3 wherein the data is restricted to include data having a pre-selected transmission mode.

6

6. The method of claim 5 wherein the pre-selected transmission mode is one of a TM3 and TM3/4 mode.

7

7. The method of claim 3 wherein the data is restricted to include data having a minimum traffic to pilot ratio.

8

8. The method of claim 3 wherein the data is restricted to include data having a specified modulation and coding property.

9

9. The method of claim 1 wherein the interference information provided by the user entity includes information relating to interference signals observed by the user entity.

10

10. An apparatus configured for wireless communication, the apparatus comprising: at least one processor; and a memory coupled to the at least one processor, wherein the at least one processor is configured: to provide, by a user entity, interference information to a macro node, wherein the interference information provided by the user entity includes information relating to interference cancellation capabilities of the user entity, and the interference cancellation capabilities include one or more of: a restriction type of transmission and a number of transmissions that the user entity is capable of canceling; and to receive a communication scheduled by a base station, wherein the communication is conveyed on a quasi-ABS which includes information corresponding to at least one macro set of data from the macro node, said macro set being made active on the quasi-ABS based at least in part on the interference information.

11

11. The apparatus of claim 10 wherein the processor is further configured to cancel interference corresponding to information which is included in the at least one macro set.

12

12. The apparatus of claim 11 wherein the at least one macro set includes a restricted data transmission from the macro node.

13

13. The apparatus of claim 10 wherein the interference information provided by the user entity includes information relating to interference signals observed by the user entity.

14

14. A method of wireless communication, comprising: receiving access to a plurality of subframes from a macro node, wherein at least one of the plurality of subframes includes at least one quasi-ABS which includes information corresponding to at least one macro set of data from the macro node; and scheduling the at least one quasi-ABS to be used by a range expansion user entity, wherein scheduling the at least one quasi-ABS, including: scheduling at least one user entity to utilize a quasi-ABS having a first set of macro sets of data from the macro node, and scheduling a different user entity to utilize a quasi-ABS having a second set of macro sets of data from the macro node.

15

15. The method of claim 14 further comprising providing interference information to the macro node.

16

16. The method of claim 15 wherein interference information includes information relating to interference cancellation capabilities of one or more range expansion user entities.

17

17. The method of claim 14 further comprising: receiving an updated plurality of subframes from the macro node; and updating scheduling procedures in response to changes in the received plurality of subframes.

18

18. An apparatus configured for wireless communication, the apparatus comprising: at least one processor; and a memory coupled to the at least one processor, wherein the at least one processor is configured: to receive access to a plurality of subframes from a macro node, wherein at least one of the plurality of subframes includes a quasi-ABS which includes information corresponding to at least one macro set of data from the macro node; and to schedule the at least one quasi-ABS to be used by a range expansion user entity, including: scheduling at least one user entity to utilize a quasi-ABS having a first set of macro sets of data from the macro node, and scheduling a different user entity to utilize a quasi-ABS having a second set of macro sets of data from the macro node.

19

19. The apparatus of claim 18 wherein the processor is further configured to provide interference information to macro node.

20

20. The apparatus of claim 19 wherein interference information includes information relating to interference cancellation capabilities of one or more range expansion user entities.

21

21. The apparatus of claim 18 wherein the processor is further configured: to receive an updated plurality of subframes from the macro node; and to update scheduling procedures in response to changes in the received plurality of subframes.
